The most fundamental tool needed to administer an HPC system is a parallel shell, which allows you to run the same command on a series of nodes. In this article, we look at pdsh.
... . Although some of these tools might not be appropriate or useful for HPC, I included them for the sake of completeness. (Note: I have not tested all of these tools, so I can’t vouch for them ...

In previous articles, I examined some fundamental tools for HPC systems, including pdsh [1] (parallel shells), Lmod environment modules [2], and shared storage with NFS and SSHFS [3]. One remaining ... One way to share HPC systems among several users is to use a software tool called a resource manager. Slurm, probably the most common job scheduler in use today, is open source, scalable, and easy

One of the key bottlenecks for HPC application performance is memory bandwidth: literally, how fast you can get data from memory to the processor and back. A convenient microbenchmark named Stream ...
After a while, everyone in HPC realizes that as technology changes, we're just moving performance bottlenecks to different places in the system as a whole. We'll never get a perfect system ...
